Poultry nutrition - Other additives
Alternative feed additives have promising importance in broiler production due to the ban on the use of certain antibiotics. The most used antibiotic alternatives in broiler production are phytogenics, organic acids, prebiotics, probiotics, enzymes, and their derivatives. Antibiotic alternatives have been reported to increase feed intake, stimulate digestion, improve feed efficiency, increase growth performance, and reduce the incidence of diseases by modulating the intestinal microbiota and immune system, inhibiting pathogens, and improving intestinal integrity. Simply, the gut microbiota is the target to raise the health benefits and growth-promoting effects of feed additives on broilers. Therefore, naturally available feed additives are promising antibiotic alternatives for broilers.
There is increasing evidence that supplementing small amounts of prebiotic xylo-oligosaccharides (XOS) into poultry diets has positive effects on bird performance and gastrointestinal health. Soluble XOS that reach the caeca intact are utilised by beneficial bacteria, inducing positive effects such as increased production of short chain fatty acids (Aachary & Prapulla, 2011). Commercial endo-xylanases are added to diets to reduce digesta viscosity, but have the side effect of producing...

Creamino® is a natural source of energy in animal nutrition. With Creamino® we provide a creatine solution for animals and relief the animal from own creatine synthesis. Creatine is important for energy supply not only in muscle cells but also in macrophages and in the heart. Therefore, with Creamino® we supply energy as well for the immune system and stress tolerance. ...

1. Introduction Coccidiosis is a major enteric infection of poultry that is estimated to cost more than USD 14.5 billion annual losses globally [1]. Although coccidiosis control using various anticoccidial chemicals, such as ionophores, coccidiocides, and coccidiostats, has long been a mainstream strategy in modern poultry production, alternative control strategies to antibiotics are necessary owing to the antibiotic ban [2]. Therefore, much effort has been made to develop...

Introduction The need for the animal sector to create ever-more-sophisticated strategies for producing animal protein in increasingly environmentally and economically responsible ways is growing. In addition to setting up ethical and environmentally friendly structures for subsequent generations, this is done to ensure that food is safe for consumption today [1, 2]. The incorporation of feed additives to accomplish these objectives has grown increasingly crucial as regulations...

Introduction High cost of conventional ingredients such as maize as source of energy, soybean, groundnut cake and fish meal as source of protein in broiler’s diet has increased the cost of feed and consequently increased cost of production (Attia, 2015). The cost of feed represents about 75% of the total costs of animal production. Also, non-availability and competition existing among man, industry and livestock have necessitated the need to find cheap and available...

Optimal soybean (SB) processing conditions is essential to ensure that antinutritional factors as trypsin inhibitors are deactivated while maintaining protein solubility and dispersibility. Heat processing is critical for improving amino acid digestibility of extruded SB for broilers. Excessive heat treatment can lead to denaturation of proteins, resulting in a negative impact on animal performance and microbiota composition. In this study, we investigated the effect of three different...

Nutritionists have access to various ingredients that fulfill methionine (Met) requirements of broilers. Amino acids (AA), such as DL-methionine, are nearly 100% bioavailable while methionine hydroxy analogs are shown to be relatively less bioavailable. Thus, this experiment aimed to determine the efficacy of using a 65% DL-methionine and 35% limestone dilution product (65DLM) compared to a methionine hydroxy analog (MHA) product when included in a diet deficient in total sulfur AA. A...

Producers are concerned about the economic impact of dietary energy costs in broiler production, as feed expenses amount to nearly 50% of the total costs. As such, reducing dietary energy costs while improving the feed conversion ratio (FCR) has been a focus of poultry producers for many ...

Arabinoxylans (AX), a non-starch polysaccharide (NSP) and poorly digestible plant cell wall component, is by far the most important anti-nutritional factor in raw materials such as wheat and corn. Due to its abundance, location in the plant material and molecular structure, AX reduces feed digestibility considerably. Firstly, water-soluble AX will increase the viscosity of the digesta in the lumen, making digestion and absorption of nutrients extremely difficult. Also, unfavorable...

The dynamic complexity of the developing embryo requires the maintenance of differentiated compartments with the capacity to maintain independent environments required to optimise their function. One of the least understood homeostatic mechanisms in embryonic development relates to the pH. The albumen’s pH at lay experiences a sharp increase to 9.7 which later decreases to 6.90 by day 17 (Tona et al., 2001). In contrast, the pH of yolk starts with a relatively low 6.67 at lay and...

The aim of this study was to evaluate the impact of feeding xylo-oligosaccharides (XOS), xylanase (XYL) and fermentable fibre, in the form of wheat bran (WB), on egg quality. It is theorised that WB stimulates and trains the microbiota in the hindgut to hydrolyse and ferment dietary xylan, and XOS and XYL may further upregulate xylan fermentation pathways, resulting in improved nutrient utilisation and thus egg quality. Isa Brown hens (n = 96 hens) were obtained at peak lay (39 weeks of age)...
